My boxes are all up now and ready for action, they are all from CJ wildlife, the tree box remains the same. The other two are 28mm and 32mm with sloping roofs which create a good angle for the camera, I also have a Robin box. I have recently found out that the neighbours box has been removed and replaced with a bug hotel, Im not complaining I have a little rooster in the tree box, not sure whether male or female yet, just arrived two nights ago 2021 is getting close. All ready here in Yorkshire!
